- News on the TSDRAW package by Timo Salmi in reverse order

-
- University of Vaasa, Finland, Sun SPARCstation IPX garbo.uwasa.fi
- has a large collection of PD and shareware PC programs available by
- anonymous ftp or mail server. The file /pc/ts/0news-ts contains news
- about the TS-programs in the /pc/ts directory (in reverse order).
- This text, which you now have, is an extract from the 0news-ts file.

- Fri 5-Nov-93: I have again updated my graphics drawing package to be
- garbo.uwasa.fi:/pc/ts/tsdraw16.zip. I have added an EGA version
- DRAWLEGA.EXE with the full 16 set of color choice. The still
- retained "DRAWLINE.EXE Draw and solve equations & lines" is a CGA
- version with four color choices. The latter will still be useful
- since the CGA version uses much larger text type, and that is useful
- in applying the program on lectures with an overhead projector.
- I also corrected the line drawing command, since "li 0,0,0"
- caused a division by zero.
-
- Sun 17-Oct-93: I have updated my graphics drawing package. It is
- especially well suited for teaching linear equations and linear
- programming, but it can be used even from preparing "transparencies"
- for an overhead projector connected to a PC. I utilize this program
- myself on my lectures on linear programming.
- This version has only one new command, "pa" for pause. But this
- one enhancement is very convenient for displaying sequential
- drawings from prerecorded data files. I noticed the need for such a
- feature in going over my notes of my own lectures for our accounting
- and business finance students. There are two new demos, TRANS1.DRW
- and TRANS2.DRW included about the usage of the pa command.
-
- Sun 8-Sep-91: Updated my graphical drawing system for linear
- equations and Linear Programming problems to be /pc/ts/tsdraw14.arc.
- It is a complete drawing system with its own command language. To
- give a simple example you can draw the line 2x + 3y = 6 by giving
- the command li 2,3,6, and the line will be displayed on the
- coordinate system. The program has the options of entering the input
- from the keyboard or from a file. If the input is taken from the
- keyboard, the input line can now be edited (and recalled if need be)
- by using the usual line-editing keys CursorLeft, CursorRight, Home,
- End, BackSpace, Delete, Esc, and CursorUp. There are some other
- small enhancements, but this is the crucial in this update.
- The system is not actually limited to drawing lines, but that is
- what I use it for myself when teaching budgeting with linear
- programming in a classroom with an overhead projector to display the
- computer images of the relevant tasks (examples are included in the
- package). I also have a Linear Programming solution program
- /pc/ts/tslin33.arc which I use in a similar manner in teaching
- quantitative budgeting for my accounting and business finance
- students at the University of Vaasa.
- The drawing program requires at least a CGA graphics adapter but
- other than that there are no special requirements. The size of the
- drawing program executable is about 90K.
- To get started after you have extracted the files from the
- package, first call DRAWLINE at the MsDos prompt, and then give eg
- the command ld multibre to have a demonstration of a multi-product
- break-even analysis. You can also enter ? or help for a quick list
- of commands.
